'' To ca-"whom it may concern: I Be it known that I, J AMES A. GRAY ,'8.c1t1- in the county-of Franklin and State of New 8 York, have invented"new and useful Im provementsin Train-Stopping Apparatus,

. 1 of which the following is a specification. This invention relates toimprovements in train stopping apparatus andin the present instance isdirected to an automatic apparatus designed to be operated-from the roadI s a1.

' n carrying out the resent invention it is my purpose to p'rov'i e. anautomatic tram l5 -stoppi'ng. apparatus whereby the throttlevalve of theengine will be closed and the en- 'gi neers" air brake valve moved. to;a position to effect anapplication of the brakes to the wheels from oneof the axles of a car, 'said movementsbf the throttle and airbrakevalves from the 'axle-being-dependent upon theposition of the'roadsignal. I

It' is also my purpose to. provide an apconjunction'with anytype ofsignal without necessitating thealteration fof' such system and wherebythe. tram will be'- automatically brought to a standin "the event of theengineer, through negligence or otherwise, failing to observev thedangersignal. g 4 Furthermore, I- aim to provide atram stoppingapparatus which will be entirely. automatic moperation' and which Wlllpermit' the throttle valve and theengine'ers air brake valve to bemanually operated in the normal or inactive position of the apparatus.The'inventio'n has for a further object the provisionof an apparatus ofthe .type set forth which-will embrace the desired free- I tures ofsimplicity, efliciency and durabil tycoupled with cheapness of cost inmanufacture and installation and which may be readily applied .to anycharacter of locomotive.- With the above and other objects n view, theinvention consists in'the construction; combination and arrangementof-parts hereinafter set forth inandjfalling within the sco eo'f'theclaims.

Referring now to .the'accompanying drawings in. detail, a conventional,form 'of locomotive is indicated at A, while the numerals 1' and 2respectively designate the throttle valve rod and airbrake handle. 7 0-Suitablyfaste'ned to the boiler head'within the engine cab is a bedplate 3 andjour-z naledin alining bearings carried liv such bed plateis-ahorizontal shaft 4- formed'of axially alining sections 5 and 6.Surrounding 76 the confronting or meeting ends of the sections 5 and 6of the shaft lsa loose pulley 7 I upon the respective sections i theshaft at opposite-sides of theloose .pul ley are fast pul eys 8 and 9.In the present -.80 mstance, the free end of. each section 5, 6 hassuitably fastened thereto a gear wheel 10 and a drum 12.

In this inthe path of movement of the danger signal 15 stance,I employ two belt shifters 25, 25

sothat upon contacting with such signal which extend outwardly fromopposite sides the respective belt shifter will be rendered of theengine cab and each belt shifter is held operative to throw the beltfrom the loose against operation by means of a trip 27 pulley 7 onto thefast pulley 8 of the section pivoted upon an appropriate part of the cab5, thereby throwing the throttle valve and and adapted to be moved outof the path of operating the engineers brake valve,through the shifterrod upon contacting with a sigthe medium of the gear wheel 10 and the'nal set to danger.

This dish is formed with an From the foregoingdescription talrenin opening alining with the" channel 31 and passedthrough such opening and slidably 10 disposed within the casing is aplunger 32 having a reduced stem 33 disposed Within the channel 31, acoiled expansion spring 34: encircling the plunger and abutting at oneend against the adjacent face of the disk 31 1 and having'its oppositeend in engagement with a pin 36 carried by the plunger, the springnormally acting to force the reduced shank 33 of the plunger outwardlyof the outer end of the casing. A trigger or trip 27 is pivoted upon theouter end of the casing 30 and normally lies in the path of movement ofthe shank 33 of the plunger so as to hold the latter against movementunder the action of the spring, while to the inner end of the plunger.is connected one end of the shipper rod of the belt shifter, theopposite end of the latter being looped to encircle the belt. Thus, itwill be seen that when the trigger or trip 27 is contacted by thesignal, the plunger will be released so that the spring 85 may slide thelatter within the casing and so shift the belt. Although I have shownand described one particular form of belt shifter, it is to .be 2
